ABSTRACT

A method for safeguarding confidential information during a screen share between two computing devices each having a screen. The method includes receiving, from a first computer, a request to share content of one or more applications displayable on a screen of a second computer. The method further includes summarizing the content to be displayed by the one or more applications, and transmitting, by the first computer, the summarized content to be shared by the one or more applications with the second computer. In exemplary embodiments, the summarized content may be password protected. The method may further include prompting, by the second computer, a password entry and displaying, by the second computer, the summarized content based on a password match.

BACKGROUND

Embodiments of the present invention relate generally to the field ofcomputing and more particularly to data processing and protectingconfidential information during a screen sharing session betweenmultiple users.

Screen sharing is a common way for two or more users to workcollaboratively with each other or to communicate interactively. Theavailability of instant messenger chat programs and web-conferencing,together with document sharing, has led to closer working relationshipsbetween employees, even if those employees may be sitting in offices onopposite ends of the world. In many work environments, two or moreemployees currently have the option to share a computer screen withanother member of their team, thereby fostering a closer workingrelationship as well as increasing the chances of revealing confidentialdocuments, emails, or other private information that may be open duringa screen sharing session.

Oftentimes, a user may not pay close attention to content they aresharing, or perhaps not even realize that confidential information iscontained within the content they are sharing. This may be due to a userbeing in a rush, or simply being careless.

Currently, there is no mechanism to automatically hide confidential orprivate information that a user is sharing during a screen sharingsession.

DETAILED DESCRIPTION

Currently, there is existing software such as IBM SameTime® (SameTime isa registered trademark of IBM Corporation) meeting room that allows theuser to share either their whole screen or just a file. Furthermore,there are additional precautions that must be considered when a usershares either their screen or a file.

The present invention can intelligently share a user screen, or file,with message composition styles to prevent the user from sharing privateor confidential information by accident. For example, sometimes a usermay not intend to have certain private applications open on theirdesktop during a screen share, or send a particular file to a recipient.Other times, a recipient may have other people in the room who are notintended recipients of the shared information.

Some of the message composition style techniques disclosed by thepresent invention may include only sharing a few keywords in the screenshare session, rather than a full message. In this instance, a sendercan choose to expand the full message through additional menu selectionsor a mouse click. This safety measure provides a second look for thesender in order to ensure that the sent message, or file, is the correctmessage or file for the intended recipient.

Another message composition style technique disclosed by the presentinvention may include only displaying a code name that can be understoodbetween the sender and the receiver, or popping up a small avatar to askthe receiver whether it is OK to currently share the screen.

Hereinafter, exemplary embodiments of the present invention will bedescribed in detail with reference to the attached drawings.

The present invention is not limited to the exemplary embodiments below,but may be implemented with various modifications within the scope ofthe present invention. In addition, the drawings used herein are forpurposes of illustration, and may not show actual dimensions.

FIG. 1 illustrates a screen sharing computing environment 100, inaccordance with an embodiment of the present invention. Computingenvironment 100 includes first computing device 110, second computingdevice 130, and database server 140 all connected via network 102.

In the example embodiment, first computing device 110 contains userinterface 112, application 114 a, and screen sharing protection program120. In various embodiments, first computing device 110 may be a laptopcomputer, tablet computer, netbook computer, personal computer (PC), adesktop computer, a personal digital assistant (PDA), a smart phone, orany programmable electronic device capable of communicating with secondcomputing device 130 and database server 140 via network 102. Firstcomputing device 110 may include internal and external hardwarecomponents, as depicted and described in further detail below withreference to FIG. 5. In other embodiments, first computing device 110may be implemented in a cloud computing environment, as described inrelation to FIGS. 6 and 7, herein. First computing device 110 may alsohave wireless connectivity capabilities allowing it to communicate withsecond computing device 130 and database server 140, as well as othercomputers or servers over network 102.

In an exemplary embodiment, user interface 112 may be a computer programthat allows a user to interact with first computing device 110 and otherconnected devices via network 102. For example, user interface 112 maybe a graphical user interface (GUI). In addition to comprising acomputer program, user interface 112 may be connectively coupled tohardware components, such as those depicted in FIG. 5, for receivinguser input. In an example embodiment, user interface 112 is a webbrowser, however in other embodiments user interface 112 may be adifferent program capable of receiving user interaction andcommunicating with other devices.

In an exemplary embodiment, application 114 a may be a computer program,on first computing device 110, that is capable of communicating withanother computer, such as second computing device 130. In an exemplaryembodiment, application 114 may be an instant messenger service on firstcomputing device 110 that is capable of sharing a computer screen withother users, receiving and/or sending data files, instant messaging,web-conferencing with a group of one or more users, or sharinginformation on first computing device 110 with second computing device130 via any other known method to one of ordinary skill in the art. Inexemplary embodiments, data files may include, but are not limited to,word processing files, video files, audio files, graphics files, and soforth.

In an exemplary embodiment, application 114 is depicted in FIG. 1 asapplication 114 a on first computing device 110, and as application 114b on second computing device 130 thereby illustrating that application114 is the same on both first computing device 110 and computing device130. For example, a first user, on a first computing device 110, mayutilize the functionality (e.g. screen share, file transfer) of aninstant messaging application only if a second user, on a secondcomputing device 130 also has the same instant messaging application.

In an exemplary embodiment, screen sharing protection program 120contains instruction sets, executable by a processor, which may bedescribed using a set of functional modules. The functional modules ofscreen sharing protection program 120 include data analysis module 122,data summarization module 124, and information delivery module 126.

With continued reference to FIG. 1, second computing device 130 containsuser interface 132 and application 114 b may be a laptop computer,tablet computer, netbook computer, personal computer (PC), a desktopcomputer, a personal digital assistant (PDA), a smart phone, or anyprogrammable electronic device capable of communicating with firstcomputing device 110 and database server 140 via network 102. Whilesecond computing device 130 is shown as a single device, in otherembodiments, second computing device 130 may be comprised of a clusteror plurality of computing devices, working together or workingseparately. Second computing device 130 may be implemented in a cloudcomputing environment, as described in relation to FIGS. 6 and 7,herein. Second computing device 130 may also have wireless connectivitycapabilities allowing it to communicate with first computing device 110and database server 140, as well as other computers or servers overnetwork 102.

In an exemplary embodiment, user interface 132 may be a computer programthat allows a user to interact with second computing device 130 andother connected devices via network 102. For example, user interface 132may be a graphical user interface (GUI). In addition to comprising acomputer program, user interface 132 may be connectively coupled tohardware components, such as those depicted in FIG. 5, for receivinguser input. In an example embodiment, user interface 132 is a webbrowser, however in other embodiments user interface 132 may be adifferent program capable of receiving user interaction andcommunicating with other devices.

With continued reference to FIG. 1, database server 140 includesapplication content sharing history database 142 and may be a laptopcomputer, tablet computer, netbook computer, personal computer (PC), adesktop computer, a personal digital assistant (PDA), a smart phone, aserver, or any programmable electronic device capable of communicatingwith first computing device 110 and second computing device 130 vianetwork 102. While database server 140 is shown as a single device, inother embodiments, database server 140 may be comprised of a cluster orplurality of computing devices, working together or working separately.

In an exemplary embodiment, application content sharing history database142 may store an application type, a shared data file type, sharingfrequency, communication history, and so forth which may be depicted asa data model. For example, the data model may identify the content ofthe shared data file (e.g. whether the application content is text,graphics, images, or video), whether it is possible to have a summarizedor shortened message (e.g. 1 for “yes”, 0 for “no”), recipient, andfrequency. As such, a data model stored in application content sharinghistory database 142 may appear as <JPEG, 1, user3, 5>.

In further embodiments, application content sharing history database 142may store an application sharing history organized by recipient, type offile, and screen sharing protection in place to protect private orconfidential information for a particular file or application. Inalternative embodiments, application content sharing history database142 may be organized in any fashion deemed most useful for the inventionto be utilized.

In various embodiments, application content sharing history database 142may be stored on first computing device 110 as a separate database.

FIG. 2 is a flowchart illustrating the operation of screen sharingprotection program 120, in accordance with an embodiment of the presentinvention.

Referring now to FIGS. 1 and 2, screen sharing protection program 120may detect a screen share of one or more applications having content andsafeguard confidential information from being inadvertently revealedduring a screen share.

With continued reference to FIGS. 1 and 2, data analysis module 122includes a set of programming instructions in screen sharing protectionprogram 120. The set of programming instructions is executable by aprocessor. Data analysis module 122 receives, from a first computingdevice 110, a request to share content of one or more applicationsdisplayable on a screen of a second computing device 130 (step 202). Forexample, one or more applications may be a text document, a power-pointpresentation, a spreadsheet, an image, or any other type of softwaremedium that may be shared, and displayed, electronically with anothercomputing device.

In an exemplary embodiment, data analysis module 122 analyzes whichapplications, or which portion of the computer screen of first computingdevice 110, tend to be shared the most during a screen sharing sessionwith second computing device 130. Data analysis module 122 may detectthe nature of the one or more applications to be shared during a screensharing session with second computing device 130, for example theapplication may be an e-mail client, an instant messaging client, a wordprocessing client, or a software development integrated developmentenvironment (IDE) client.

In exemplary embodiments, data analysis module 122 determines which ofthe one or more applications contain either a lot of text or graphics,or essentially a lot of content. A lot of content within an applicationmay increase the chance of a user sharing information that isconfidential. In exemplary embodiments, data analysis module 122 maydetermine a lot of content within an application by detecting a wordcount, a file size, and/or analyzing metadata of an application.

Data analysis module 122, in exemplary embodiments, may determine whichapplication is suitable for shortening (i.e. summarizing) text contentor graphical content in an application. For example, an e-mail client'stext may be shortened through enabling technology, while source code inan IDE may be more difficult to be summarized.

With continued reference to FIGS. 1 and 2, data summarization module 124includes a set of programming instructions in screen sharing protectionprogram 120. The set of programming instructions is executable by aprocessor. Data summarization module 124 summarizes the content to bedisplayed by the one or more applications (step 204). Summarization ofcontent within an application may simply be taking the subject line ofan e-mail, for example, and displaying only that portion of the e-mail.In other embodiments, summarization may include performing a naturallanguage text analysis of a text document and displaying a span of thetext that includes a general concept, or idea, without including anysensitive or confidential information (e.g. names, numbers, locations),such as specific information about the general concept. In yet otherembodiments, summarization of an image or video may include performingimage analysis techniques to display only a generic thumbnail of aportion of the image, or video.

In exemplary embodiments, data summarization module 124 may determinethat the received content contained within one or more applications maycontain confidential content. As such, data summarization module 124 maybe capable of summarizing the content of the one or more applicationscontaining confidential content. Applications that may containconfidential content may include a web browser, an instant messagingapplication, a work/private e-mail account, just to name a few. Theseapplications contain potentially confidential content, since, if leftopen a user's desktop, may disclose confidential information on a screenshare with a second computing device 130. Examples of confidentialcontent within these applications may include a business spreadsheet, aprivate website, an e-mail discussing confidential work-related matters,a private instant message chat discussing a confidential project, taxinformation, medical information, and so forth.

In another exemplary embodiment, data summarization module 124 may becapable of allowing the user who shares the content of one or moreapplications displayed on their computer screen (i.e. of first computingdevice 110) to further highlight the currently summarized content (e.g.text, graphics, video), with recipients of the content of the one ormore applications displayed on the screen of second computing device130, by selecting a context menu to expand the summarized content tofull content as needed, on the fly.

FIG. 3 depicts a shared computer screen containing summarized content ofa slide in a power-point presentation, in accordance with an embodimentof the present invention.

With reference to FIGS. 1-3, second computing device 130 may receive thesummarized content shared by the one or more applications and displaythe summarized content on the computer screen of second computing device130.

In alternative embodiments, and with continued reference to FIGS. 1-3, auser on computing device 110 may be sharing the content of one or moreapplications displayed on her computer screen, for example a power-pointpresentation, in a web conference with multiple users using multiplecomputing devices, including second computing device 130, at once. Someof the users may not be privy to viewing some of the informationpresented. In this scenario, data summarization module 124 may onlydisplay a summarized content of the slide, for example “SoftwareFunctional Specification”, rather than the entire power-point slide. Inthis scenario, the users with clearance to view the full slide may needto input a password to unlock the slide contents. Alternatively, theuser sharing the screen may have the option to lock/unlock thesummarized content for a pre-configured list of recipients of the screenshare.

With continued reference to FIGS. 1-3, in exemplary embodiments, thesummarized content of an application may be password protected, whereindata summarization module 124 prompts a request to view the summarizedcontent shared by the one or more applications. Second computing device130 may display the summarized content based on a password match enteredby a user of second computing device 130.

In another exemplary embodiment, the user who shares content of one ormore applications displayed on the computer screen may click on thelock/unlock button to reveal the password protected (i.e. locked)summarized content (e.g. text, graphics, video) and select a contextmenu to expand the content to full content as needed on the fly. Thismechanism prevents unwanted disclosure of confidential or privateinformation and provides the user, who is screen sharing the displayedcontent, with additional control over the content on the screen share.

In an exemplary embodiment, data summarization module 124 may provide auser of the first computing device 110 with an option to select acontext menu to expand the summarized content to full content, asneeded, or to contract the full content back to the summarized content,as needed.

With reference to an illustrative example, user A may be engaged in ascreen sharing session with user B. Data summarization module 124 maydetect that user A has unintended open documents, or applications,displayed on his shared screen, and summarize the content within thosedocuments/applications. Furthermore, data summarization module 124 maysummarize the content of an application that user A intended to sharewith user B. This feature may prevent unintended disclosure ofconfidential, or private, content based on user A's oversight, orcarelessness. In this embodiment, user A maintains full control over thedisplayed content on her screen by controlling the expanding, orcontracting, of the summarized content of shared documents/applicationsby the click of a mouse, for example. In exemplary embodiments, user Amay have the option to turn on/off the data summarization feature at anytime.

FIG. 4 depicts a shared computer screen containing full content of aslide in a power-point presentation, in accordance with an embodiment ofthe present invention.

With reference to FIGS. 1-4, in alternative embodiments, datasummarization module 124 may share the summarized content of firstcomputing device 110 with second computing device 130, and require apassword match, entered by a user of the second computing device 130, toreveal, or share, the content of the one or more shared applications.FIG. 4 depicts a screen share of an application, from computing device110, to a user of second computing device 130 who successfully enters apassword to access the full content of the power-point slide.

In alternative embodiments, data summarization module 124 may determine,by natural language processing, that the received content of the one ormore applications contain confidential content, wherein the confidentialcontent comprises any one of a personal name, address, bank information,telephone number, date of birth, and social security number, or anycombination thereof, and summarizes the confidential content. Forexample, natural language processing techniques, within datasummarization module 124, may be capable of crawling text within sharedcontent of an application and summarizing the discovered confidentialcontent, for example by replacing it with the appropriate words, such as“Name”; “Private bank information”; “Private SS information”; and soforth.

In alternative embodiments, data summarization module 124 may be capableof blurring, removing, or covering up confidential content discovered bynatural language processing techniques.

In alternative embodiments, data summarization module 124 may expand asummarized content to full content during a screen share with secondcomputing device 130, and revert the full content back to the summarizedcontent upon detecting a user is away from the second computing device130. For example, data summarization module 124 may be capable ofdetecting idle time of computing device 130 and if a certain thresholdof idle time is reached, the full content share may revert back to thesummarized content, thus avoiding potentially sensitive content fromremaining open on a computer screen of second computing device 130 whena user may have walked away from the computer.

In another alternative embodiment, data summarization module 124 mayrequire a user of second computing device 130 to re-enter a password ifa certain threshold of idle time has elapsed without any keyboardstrokes. In yet another alternative embodiment, data summarizationmodule 124 may end a screen sharing session altogether if determinedthat the second computing device 130 is idle for a certain threshold oftime.

In another alternative embodiment, data summarization module 124 mayrevert the full content of a screen share back to a summarized contentbased on second computing device 130 detecting that a user has movedaway from the keyboard, via a camera on second computing device 130.Detection of a user moving away from second computing device 130 mayalso be determined by picking up a change in the lighting of a room, viathe computer camera or light sensors on second computing device 130,which may indicate that a user has left the room.

With continued reference to FIGS. 1 and 2, information delivery module126 includes a set of programming instructions in screen sharingprotection program 120. The set of programming instructions isexecutable by a processor. Information delivery module 126 transmits, bythe first computing device 110, the summarized content, to be shared bythe one or more applications, with the second computing device 130 (step206).

In exemplary embodiments, information delivery module 126 may determinewhether it is acceptable to share the summarized content based on a userat second computing device 130 indicating that it is acceptable toshare. Based on the user at second computing device 130 indicating it isacceptable to proceed with a screen share, information delivery module126 may transmit the summarized content to be shared by the one or moreapplications. For example, information delivery module 126 may pop up anavatar on second computing device 130 to ask the receiver if it is OK toshare the screen at the current time. This safety measure may prevent anunwanted screen share, or private message, when there may be otherpeople around or if the user is engaged in a different screen share withother user(s).

In an exemplary embodiment, information delivery module 126 may replacethe summarized content with a code name when the second computing device130 is engaged in a different screen sharing session at the time ofreceiving the summarized content, wherein the code name is based on acommunication history between the first computing device 110 and thesecond computing device 130. A code name may include a word, a sentence,or a phrase that may refer to a specific document, conversation, topic,etc. that the user of the second computing device 130 may recognize. Forexample, a user on second computing device 130 may receive an instantmessage from a user on first computing device 110 referencing a priorconfidential instant messaging conversation from earlier that day. Acode name (e.g. “Earlier conversation” or “Business project”) may conveythe topic of the conversation, or a reference to the prior conversation,without revealing any confidential information that may accidentally beseen by a third party in the event the user on second computing device130 is currently engaged in a screen sharing session with a third party.This safety mechanism prevents the accidental, or incidental, revelationof confidential information to one or more third-parties. When thesecond computing device 130 is dis-engaged from the third-party screensharing session, the receiver may then access the information containingthe code name.
